Why are digital currency countries not regulated
on September 4, 2017, the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance", which cleaned up the ICO and virtual currency trading venues. The scale of domestic virtual currency transactions decreased significantly, effectively avoiding the impact of virtual currency prices on China's financial market.
digital currency is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank. It is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency.
As long as the influence of bitcoin scam is not particularly bad, the government generally adopts the policy that the people do not sue, the officials do not blame, and turn a blind eye to it. Because even if the government enters, it is difficult to find the culprit. The information of some operation teams is not public, and it is difficult to find it on the Internet. Some of them are still abroad, so it is difficult to solve the case. Some of the culprits turn around and become victims. There are also those who participated in the bitcoin pyramid scheme. A large number of victims are also the biggest accomplices< br />
Recently, the price of global crypto digital currency is quite unstable. Bitcoin has fallen below US $7000 from its peak of US $20000 at the end of last year, and soared by more than 11% in one day. There are huge fluctuations in the market, and there are many differences in the attitudes of countries towards digital currency. Some announced that they would issue the world's first sovereign legal digital currency, showing a "strong support" attitude, and more countries carefully observed and focused on research and guidance
the existing monetary and financial system is not a natural evolution, but an inevitable result of legal restrictions or government regulation. Although cryptocurrency has many defects, it is also a valuable experiment, especially in the exploration of super sovereign currency. Different from precious metal currency and credit currency, they are oriented to the exploration of "transaction benchmark consensus" in the data age. Of course, if it is affected by too much price fluctuation, speculation, deflation restrictions, etc., and the payment function of crypto digital currency can not be truly implemented, it can only be further and further away from the "currency experiment", or become a special basic "digital asset", or a flash in the pan in the long history

The full name of HPB is hot rolled plain steel bar (HPB is short for hot rolled plain steel bar). 300335400 refers to its corresponding yield strength
The yield strength of hpb300 is higher than that of hpb235. It is the latest national standard for grade I steel, which is used to replace the older grade I steel hpb235HRB335, hot rolled ribbed bar, i.e. grade II steel
HRB400, hot rolled ribbed bar, i.e. grade III steel

extended data
there are many kinds of steel bars, which are usually classified according to chemical composition, proction process, rolling shape, supply form, diameter, and use in structure:
(1) according to rolling shape
1 Smooth steel bar: Grade I steel bar (Q235 steel bar) is rolled into smooth round section, and supplied in the form of circle, with diameter no more than 10mm and length of 6m ~ 12m
There are three kinds of ribbed bars: spiral, herringbone and crescent. Generally, grade II and III bars are rolled into herringbone, and grade IV bars are rolled into spiral and crescent Steel wire (including low carbon steel wire and carbon steel wire) and steel strand Cold rolled and twisted steel bar: cold rolled and cold twisted(2) according to the diameter, it is divided into steel wire (diameter 3 ~ 5mm), fine steel bar (diameter 6 ~ 10mm) and thick steel bar (diameter more than 22mm)
(3) according to the mechanical properties, it is divided into grade I steel bars (grade 235 / 370); Grade II reinforcement (grade 335 / 510); Grade III reinforcement (370 / 570) and grade IV reinforcement (540 / 835) (4) according to the proction process, there are hot-rolled, cold-rolled and cold drawn steel bars, and heat-treated steel bars made of grade IV steel bars after heat treatment, with higher strength than the former (5) according to the function in the structure, it can be divided into compression reinforcement, tension reinforcement, erection reinforcement, distribution reinforcement, stirrup, etc
